SPECIFICATION forming part of Letters Patent No. 584,999, dated June 22,1897.

Application filed December 23,1893. Serial No. 494,548. (No model.)

.T7 (LZZ whom, it may concern-f Be it known that we, BYRON BENJAMINGOLDSMITH, a resident of New York, in the county and State of New York,and lVILLIAM BURT, a resident of Jersey City,county of H udson, State ofNew Jersey, have invented certain new and useful Improvements inMagazine Lead-Pencils, of which the following is a specification.

Io Our invention has reference to improvements in magazine-pencils inwhich a series of individual marking-points are stored in a magazine andby a simple manipulation of the device are forcibly projected inposition I5 for use and the used-up or broken markingpoints are forciblyejected.

A characteristic feature of our invention is that the individualmarking-points are stored in a magazine-tube which is movable longizotudinally with reference to the mantle or holder of the pencil and thatthe ejector may be either immovable with reference to the Inagazine-tubeor may also be movable with reference to and with the same. Thearrangement may be such that the movement of the magazine-tube or ofboth the magazinetube and the ejector in both directions is effectedpositively by the operator, or by preference the arrangement may be suchthat 3o only the movement in` one direction is effected positively bythe operator and the movement in the other direction is produced by aspring. These and other improvements will more fully appear from thefollowing detail description, with reference to the accompanyingdrawings, in which- Figures l, 2, and 3 represent longitudinal sectionsof one form of our magazine-pencil with amovable magazine-tube andrelatively 4o immovable ejector. Figs. 4 and 5 represent like views of amodified form of our magazine-pencil in which both the magazine-tube andthe ejector are movable with reference to and with each other. Fig-6 isa longitudinal section of a modified construction of the feeding end ofthe magazine-pencil, and Fig. 7 is an elevation of the same.

Like numerals of reference indicate like parts all throughout thedrawings.

5o Referring now particularly to Figs. 1, 2, and 3, the/ main body ofthe magazine-pencil is shown as la mantle l, which may be of wood ormetal or other suitable material, and which has mounted at the forwardend a nozzle 2 and at the rearward end a sleeve 3, the rear n edge 4 ofwhich is turned inwardly, as shown. The nozzle 2 and sleeve 3 are faston the mantle, so that they may be considered as a portion of thelatter. The rear end of the mantle proper thus forms a ledge 5, whichserves 6o as a support for a flange 6 on the ejector-tube 7, whichextends Centrally through the mantle and has formed at its forward endspringfingers S 8, which are bent inwardly for a purpose which willvpresently appear.

Through the ejector-tube7 extends the magazine-tube 9, formed at itsforward end, which projects through the nozzle 2, with spring-jaws 1010, formed in the rear of the front end with beads 1l 1l. In the normal7o position of the parts this magazine-tube is in the location shown inFig. l-that is to say, the tube is in its rearmost position, with thebeads l1 pressed against the front edge of the nozzle, so that thespring-jaws 10 are 75 thereby compressed and tightly hold an individ ualmarking-point l2. This magazinetube is so long that with its rear end itprojects beyond the sleeve 3. It has a free opening at that end, throughwhich the series of So individual marking-points are fed into themagazine-tube. Loosely fitted into the sleeve 3 is the pushpiece 13.This is a tube of a diameter to push through the inturned edge 4 of the85 sleeve 3, but having the inner end expanded, as shown at 14, so as toloosely t the inner face of the sleeve. In this manner there is anoffset or ledge formed between the wider and the narrower portions ofthe push-piece, 9o whereby the latter is prevented from being drawn outof the sleeve 3, but can be moved freely to and fro in said sleeve. Uponthe magazine-tube there is iixed a disk or washer 15, and between thisdisk or Washer and the flange 6 on the ejector-tube and surrounding themagazine-tube is inserted ahelical spring 16, which in the normalposition of the parts is expanded, thus holding the magazine-tube in itsmost rearward position with the beads 1l forced against the front edgeof the nozzle and holding the ejector-tube in its most IOO forwardposition with the flange G against the ledge 5. The ejector-tube isalways in this position the same as if it were fixed to the mantle, andit may conveniently be fixed to the sam e. In the drawings we have shownthe disk or washer 15 bearing against the offset between the wider andnarrower portions of the push-piece 13, but it may just as well be madelarge enough to bear against the inner edge of the push-piece. Thepush-piece is closed by a removable thimble 17, which thus serves as athumb-piece upon which the finger of the operator presses for forcingthe push-piece inwardly. This tliimble is removed when the magazine-tubeis to be filled.

Midway between the two ends of the ejector-tube there is formed in thelatter a longitudinal slot 18, into which projects a tooth 10, st-ruck up from the magazine-tube, as shown. The foiwvard-and-backward movementof the magazine-tube is thus limited by the length of the slot 18.

A short distance behind the beads 11 on the spring-jaws of themagazine-tube there are formed in the latter two diametrically oppositelongitudinal slots 2O 20, into and through which the spring-fingers 8,formed at the forward end of the ejector-tube, normally project.

Fig. 1 represents the device with the parts in their normal positions.It shows the magazine-tube filled with individual markingpoints, but theparts are in the same position as when the magazine-tube is empty. Themagazine-tube is filled, as above stated, by removing the thimble 17 andthen dropping the marking-points down into the tube with their pointsforward. The first markingpoint dropped into the tube is arrested by thespring-fingers 8 of the ejector, which spring-fingers project throughthe slots 2O into the magazine. The other inarking-points thus becomearranged in a series one behind the other, each with its point restingupon the butt-end of the preceding marker. In this condition of thedevice the magazinetube isin its rearmost position with the tooth 1f) atthe rear end of the slot 18, and it is understood that the pencil isheld vertically, or nearly so, with the forward end downward. After themagazine-tube has thus been filled, or nearly filled, the thimble 17 mayagain be put in place, and the user, grasping the mantle, presses withone of his lingers upon the thimble, thus forcing the push-piece 13inwardly, which carries with it the magazinetube and compresses thespring 16 between the flange 6 and the washer 15, as shown in Fig. untilthe tooth 1f) is arrested by the forward end of the slot 18. Themagazinetube is thereby projected through the nozzle, and thespring-fingers 8 of the ejector ride upon the solid portion of themagazine-tube and are thus withdrawn from the slots 2O 20 and do notimpede the further forward movement of the series of marking-pointsbehind the same. These marking-points, therefore,

l now drop down into the forward portion of the inagazine-tubc, without,however, dropping out of the same, since the spring-jaws l0 10 are soconstructed as to always close su fiieiently to prevent the freemovement of the markingpoints between the same. The pressure of thefinger upon the push-piece is now removed and the spring 1G, againexpanding, carries the inagazinc-tube back into the position shown inFig. l. Midway between these two positions the parts have the relationshown in Fig. S-that is to say, the tooth 19 is in about the middle ofthe slot 18, while the springfingers 8, having again passed through theslots 20, bear upon the butt-end of one of the marking-points. As themagazine-tube still further retreats, the markingpoints in front of thespring-fingers of the ejector are held stationary and the magazinetubeis drawn back over the saine until the foremost marking-point isprojected in position for use between the spring-jaws 10 10, which nowtightly close upon that forward marking-point by reason of the beads 1111 bearing upon the front edge of the nozzle. A repetition of thereciprocating movement of the magazine-tube operates, in conjunctionwith the ejector, to forcibly eject the foremost marking-point and toforcibly project the one immediately behind it in position for use.

It will now be understood how a forward marking-point, after having beenused up so as to become dull, can be ejected forcibly and how a newpoint is projected forcibly in position for use. All that is necessaryis that the device be held with the nozzle downward and that thepush-piece be pressed down with one finger to the end of its stroke(which is limited by the slot 18 and tooth 10) and that the push-piecebe then released.

Itis not absolutely necessary that the magazine-tube in its normalposition shall project beyond the nozzle, since it may be constructed soas to be normally flush with the nozzle, in which case, of course, thebeads 11 11 will or may be omitted. In that case, however, thespring-jaws 10 10 will be made to hold the foremost marking-point, whenin position for use, sufficiently tight to prevent this point fromfalling out. If this construction is adopted without other change in theproportions of the parts, there will normally be only two points inadvance of the spring-fingers 8, but the proportions may be slightlychanged so as to have only a single marking-pointnamely, the one whichis in position for usein advance of the spring-fingers 8; or themagazine-tube may be made to normally project beyond theV nozzle, asshown, but without the beads 11, since the function of these beads isonly to cause the spring-jaws to more tightly grasp and hold the forwardmarkingpoint when the magazine-tube is in the retracted position. Thisadditional tightening may be dispensed with.

Figs. 4 and 5 illustrate another form of our IOO invention in which boththe magazine-tube and the ejector are movable relative to each other,and also movable with each other relative to the mantle or case. In thiscase the mantle 1 is preferably made of sheet metal, although it may bemade of other material. The nozzle 2, which extends rearwardly in theshape of a tube, is held in the mantle either by friction only or isotherwise secured to the same, and the same is true of the sleeve 3,which has also an inturned edge 4, as ,in the construction shown inFigs. 1, 2, and The push-piece 13 isv in this case made ratherlong andis closed by the thimble or push-button 17. The washer 15 on theejector-.tube 7 may be either soldered to the same or may simply bepassed over the same against a small bead 15' on the ejector, and thiswasher or disk 15 bears against the edge of the expanded portion of thepush-piece. A second disk or washer 15" is held on or secured to theejector-tube at a point between the forward end of the slot 1S and thespring-iingers 8, and the helical spring 16, surrounding theejectortube, bears at one end against this washer 15" and with the otherend against the ledge 2, formed in the nozzle where the same expandsinto a tube.

The magazine-tube 9 is constructed in this instance precisely like themagazine-tube shown in the other figures of drawings, except that itdoes not project in the rear beyond theV ejector-tube, but, on thecontrary, the latter projects beyond the magazine-tube. Immediately infront of the slots 2O 2O in the magazine-tube there is fixed to thelatter a small disk or washer 2l, by which the forward movement of themagazine-tube is limited, since upon such forward movement the disk 2lstri kes against the ledge 2' in the nozzle. The rearward movement ofthe magazine-tube is limited by the beads 11 striking against the frontedge of the nozzle. This is the normal position of the parts and isrepresented in Fig. 4, while Fig. 5 shows the magazine-tube in itsforward position, and consequently the disk 21 bearing upon the ledge 2.

The slots 2O and the spring-ingers 8 are so proportioned in length andrelative position that in the normal condition of the device thespring-iingers are out of the slots and bear upon the solid portion ofthe magazine-tube, and in this normal relative position themagazine-tube and ejector are held by the helical spring 16. In thatportion of the magazinetube which lies between the disk 21 and the beads11 there are struck up two springtongues 22 22e which normally projectinto the magazine-tube and bear against the butt-end of a marking-point,thereby preventing the foremost marking-point from slipping back in theact of writing.

The operation of this form of our magazinepencil will now be readilyunderstood. Supposing the parts to be in their normal position, as shownin Fig. 4, without leads in the maga-zine, the latter is iilled byremoving the thimble 17 and dropping the leads into the( tube with theirpoints downward. The first marking-point will be arrested by thespringtongues 22, and the others will arrange themselves in series, eachwith its point against the butt-end of the preceding one. The pusher isthen forced down, whereby the spring-lin gers Senter the slots 2O andproject through the same until they bear upon the butt-end of amarking-point. Continued pressure upon the push-piece causes thespringngers to press upon the forward series of marking-points, andsince the latter are held against free forward movement by thespringtongues 22 the magazine-tube is forced forwardly until the disk 21strikes against the ledge 2', as shown in Fig. 5. By this movement ofthe magazine-tube the spring-jaws 10 are relieved of the compressingaction thereon of the nozzle, which now does not bear upon the beads 1l.Still further continued pressure upon the pusher causes thespring-fingers 8 to propel the forward marking-points forwardly andbetween the springtongues 22, which close again behind the first markingpoint, preventing the rearward movement of lthe same, while the droppingout of the same is prevented by the springjaws 10, which hold itsuiiiciently tight for that purpose. By this time the spring-fingers Shave arrived at or near the end of the slots 20, while the tooth 19 isnow at the rear end of the slot 18. The forward stroke of the push-pieceis thus completed, and the finger being removed from the same the partsare returned by the spring 16 to their original position. (Shown in Fig.4.) This action is now repeated until the forward marking-point projectsfrom between the jaws 10 sufficiently for use. It will be observed thatwhen the parts are returned to their original position by the action ofthe spring 16 the foremost marking-point will be grasped very tightly bythe spring-jaws by the action of the edge of the nozzle upon the beads11. It will now be readily understood that when the first marking-pointhas been used up one stroke of the pusher will at once forcibly ejectthis marking-point and will project a new marker forcibly in positionfor use, and that all this is effected by a simple stroke of thepushpiece produced bythe pressure of a finger of the user thereon. Weare not limited to the exact details of construction thus far described,since the same may be variously changed without affecting the utility ofour magazine-pencil.

An additional improvement we have illustrated in Figs. 6 and 7. Thesaine has for its object to prevent the user from feeding the individualmarking-points into the magazinetube with their butt-ends forward, whichwith the construction shown in the preceding iigures of drawings mightbe done and which, if done, would render the pencil in a measureinoperative. This is prevented by the fol.-

lowing construction: The ejector-tube is made IOS) IlO

shorter than in the construction shown in Figs. 4 and 5, so that it willonlyslightly project beyond the lnagazine-tube, and this projectingportion is made iiaring, as indicated in solid lines at 9 in Fig. 6, andthe cap or thimble 17 is made long enough to project slightly over theHaring portion of the ejectortube. In the side of the push-piece 13there is formed a longitudinal slot 23, shaped to the shape of alongitudinal section of a markingpoint with the point downwardly, and inthe side of the thimble 17 there is formed a similar slot 24, which whenthe thimble is suitably turned will register with the slot 23. Inaddition thereto there is in the side of the thimble 17 a shortcircumferential slot 25, into which is struck a tooth 26 from the sideof the push-piece 13, thus allowing the thimble to turn to the extent ofthe length of the slot 25, but not allowing it to be removed. The partsare so placed that when the thimble is turned in one direction the slots23 and 24 register and when turned in the other direction the lateralfeed-opening is closed. Tith this construction the individualmarking-points are fed into the magazine-tube by holding the pencil inan inclined position with the point downward and dropping the individualpoints through the lateral feed-openings 23 24, when, as will now beunderstood, theyT will slide down into the magazine-tube always withtheir points downwardly, since they cannot be introduced in the slots 2324 in the reversed position. An obvious modification of thisconstruction would be to make the ej ector-tuhe as long as in theconstruction shown in Figs. 4 and 5 and make in the side of that tubeanother slot similar in shape to the slots 23 24, and this is indicatedin dotted lines in Fig. 6. In this construction the thimble must beturned in its bearing, which requires some little force, and it istherefore preferable to make the head of the thimble with milled beads,as shown. Such milled beads may also be used in the other constructionshown to facilitate the removal of the thimble 17.

It will be evident that some features of construction shown in Figs. 1,2, and 3 may be transferred to the form of pencil shown in Figs. 4 and5, and vice versa. Thus, for instance, while we have shown in Figs. 1,2, and 3 the actuating-spring 16 placed at the rear end of the penciland in Figs. 4 and 5 placed at the front end of the pencil, thesepositions may be reversed. The springtongues 22 shown in the pencilillustrated in Figs. 4 and 5 may also be used in the construction shownin Figs. 1, 2, and 3, whereby the spring-fingers S would be relieved ofthe back pressure of the pencils in the act of writing. The lateralfeed-openin g shown in Figs'. 6 and 7 may be used in connection withboth forms of pencil, and numerous other variations will suggestthemselves readily to those skilled in the art. Thus, for instance, thespring 16 may be altogether dispensed with, in which case themagazine-tube is moved both forwardly and backwardly by hand. Theforward movement would then be effected by the pressure of the iin gerupon the push-piece, as in the case when the spring 1G is used, and ismoved rearwardly by taking hold of the projected magazine-tube at thejaws 10 and sliding it back into the mantle. In that case of course theejector-tube must be fixed in the mantle positively in any suitablen'ianner, since otherwise, the spring 16 being absent, it would or mightmove with the magazine-tube, which would render the device inoperative.It will also be seen that when the spring 16 is dispensed with the actof writing will prevent the forward markingpoints from receding into themagazine-tube by vbringing the butt end of one of them against thespring-lingers S on the ejector or against the spring-tongues 22, as thecase may be.
